1bdb78368f ASoC: Updates for v6.3
There's been quite a lot of activity this release, but not really
 one big feature - lots of new devices, plus a lot of cleanup and
 modernisation work spread throughout the subsystem:
 
  - More factoring out of common operations into helper functions
    by Morimoto-san.
  - DT schema conversons and stylistic nits.
  - Continued work on building out the new SOF IPC4 scheme.
  - Support for Awinc AT88395, Infineon PEB2466, Iron Device
    SMA1303, Mediatek MT8188, Realtek RT712, Renesas IDT821034,
    Samsung/Tesla FSD SoC I2S, and TI TAS5720A-Q1.

0d9eb7ed95 ALSA: fireface: add field for the number of messages copied to user space
Current structure includes no field to express the number of messages
copied to user space, thus user space application needs to information
out of the structure to parse the content of structure.

This commit adds a field to express the number of messages copied to user
space since It is more preferable to use self-contained structure.

Kees Cook proposed an idea of annotation for bound of flexible arrays
in his future improvement for flexible-length array in kernel. The
additional field for message count is suitable to the idea as well.

8ec2d95f50 ASoC: Updates for v6.2
This is a fairly sedate release for the core code, but there's been a
 lot of driver work especially around the x86 platforms and device tree
 updates:
 
  - More cleanups of the DAPM code from Morimoto-san.
  - Factoring out of mapping hw_params onto SoundWire configuration by
    Charles Keepax.
  - The ever ongoing overhauls of the Intel DSP code continue, including
    support for loading libraries and probes with IPC4 on SOF.
  - Support for more sample formats on JZ4740.
  - Lots of device tree conversions and fixups.
  - Support for Allwinner D1, a range of AMD and Intel systems, Mediatek
    systems with multiple DMICs, Nuvoton NAU8318, NXP fsl_rpmsg and
    i.MX93, Qualcomm AudioReach Enable, MFC and SAL, RealTek RT1318 and
    Rockchip RK3588
 
 There's more cross tree updates than usual, though all fairly minor:
 
  - Some OMAP board file updates that were depedencies for removing their
    providers in ASoC, as part of a wider effort removing the support for
    the relevant OMAP platforms.
  - A new I2C API required for updates to the new I2C probe API.
  - A DRM update making use of a new API for fixing the capabilities
    advertised via hdmi-codec.
 
 Since this is being sent early I might send some more stuff if you've
 not yet sent your pull request and there's more come in.

ASoC: SOF: Add support to parse pin binding array from topology
Add support for parsing sink/source pin binding array
per widget from topology. The pin binding arrays will
be used to determine the source and sink queue IDs during
widget binding for widget that requires special pin binding.

An example of widget that requires special pin binding is
the smart amplifier widget, its feedback sink pin has to be
connected to a capture DAI copier for codec feedback, while
the other sink pin has to be connected to a host DAI copier.
Pin ID is required during widget binding for correct route setup.

Conversely, the pin ID for 'generic' pins is not defined in the
topology and will be allocated by the kernel dynamically. When
only one pin is supported, the pin ID shall always be zero. When
more than one pin is supported, the pin ID is determined with the
ID allocation mechanism in the kernel.

ASoC: qdsp6: audioreach: add support for more port connections
AudioReach Modules can connect to other modules using source and
destination port, and each module in theory can support up to 255 port
connections. But in practice this limit is at max 8 ports at a time.
So add support for allowing multiple port connections.

This support is needed for more detailed graphs like ECNS, speaker
protection and so.

668c3c237f sound updates for 6.0-rc1
As diffstat shows, we've had lots of developments in a wide range
 at this time; the majority of changes are about ASoC, including
 subsystem-wide cleanups, continued SOF / Intel updates and a
 bunch of new drivers (as usual), while there have been some
 significant (but almost invisible) improvements in ALSA core
 side, too.  Below are some highlights:
 
 Core:
 - Faster lookups of control elements with Xarray; normal user
   won't notice, but on the devices with tons of control elements,
   it can be visibly faster
 - Support for input validation for controls; this will harden
   for badly written drivers in general with a slight overhead
 - Deferred async signal handling for working around the potential
   deadlocks
 - Cleanup / refactoring raw MIDI locking code
 
 ASoC:
 - Restructing of the set_fmt() callbacks for making things clearer
   in situations like CODEC to CODEC links
 - Clean up and modernizing the DAI naming scheme setups
 - Merge of more of the Intel AVS driver stack, including some
   board integrations
 - New version 4 mechanism for communication with SOF DSPs
 - Suppoort for dynamically selecting the PLL to use at runtime on
   i.MX platforms
 - Improvements for CODEC to CODEC support in the generic cards
 - Support for AMD Jadeite and various machines, AMD RPL, Intel
   MetorLake DSPs, Mediatek MT8186 DSPs and MT6366, nVidia Tegra
   MDDRC, OPE and PEQ, NXP TFA9890, Qualcomm SDM845, WCD9335 and
   WAS883x, and Texas Instruments TAS2780
 
 HD- and USB-audio:
 - Continued improvement for CS35L41 (sub)codec support
 - More quirks for various devices (HP, Lenovo, Dell, Clevo)

29a249d72d ASoC: Updates for v5.20
This is a big release thus far and there will probably be more changes
 to come, it's a combination of a larger than usual crop of new drivers
 and some subsysetm wide cleanups from Charles rather than anything
 structural.  The SOF and Intel DSP code both also continue to be very
 actively developed.
 
  - Restructing of the set_fmt() callbacks to be specified in terms of
    the device rather than with semantics depending on if the device is
    supposed to be a CODEC or SoC, making things clearer in situations
    like CODEC to CODEC links.
  - Clean up of the way we flag which DAI naming scheme we use to reflect
    the progress that's been made modernising things.
  - Merge of more of the Intel AVS driver stack, including some board
    integrations.
  - New version 4 mechanism for communication with SOF DSPs.
  - Suppoort for dynamically selecting the PLL to use at runtime on i.MX
    platforms.
  - Improvements for CODEC to CODEC support in the generic cards.
  - Support for AMD Jadeite and various machines, Intel MetorLake DSPs,
    Mediatek MT8186 DSPs and MT6366, nVidia Tegra MDDRC, OPE and PEQ, NXP
    TFA9890, Qualcomm SDM845, WCD9335 and WAS883x, and Texas Instruments

ASoC: Updates for v5.20

This is a big release thus far and there will probably be more changes
to come, it's a combination of a larger than usual crop of new drivers
and some subsysetm wide cleanups from Charles rather than anything
structural.  The SOF and Intel DSP code both also continue to be very
actively developed.

 - Restructing of the set_fmt() callbacks to be specified in terms of
   the device rather than with semantics depending on if the device is
   supposed to be a CODEC or SoC, making things clearer in situations
   like CODEC to CODEC links.
 - Clean up of the way we flag which DAI naming scheme we use to reflect
   the progress that's been made modernising things.
 - Merge of more of the Intel AVS driver stack, including some board
   integrations.
 - New version 4 mechanism for communication with SOF DSPs.
 - Suppoort for dynamically selecting the PLL to use at runtime on i.MX
   platforms.
 - Improvements for CODEC to CODEC support in the generic cards.
 - Support for AMD Jadeite and various machines, Intel MetorLake DSPs,
   Mediatek MT8186 DSPs and MT6366, nVidia Tegra MDDRC, OPE and PEQ, NXP
   TFA9890, Qualcomm SDM845, WCD9335 and WAS883x, and Texas Instruments
   TAS2780.

94dfc73e7c treewide: uapi: Replace zero-length arrays with flexible-array members
There is a regular need in the kernel to provide a way to declare
having a dynamically sized set of trailing elements in a structure.
Kernel code should always use “flexible array members”[1] for these
cases. The older style of one-element or zero-length arrays should
no longer be used[2].

This code was transformed with the help of Coccinelle:
(linux-5.19-rc2$ spatch --jobs $(getconf _NPROCESSORS_ONLN) --sp-file script.cocci --include-headers --dir . > output.patch)

@@
identifier S, member, array;
type T1, T2;
@@

struct S {
  ...
  T1 member;
  T2 array[
- 0
  ];
};

-fstrict-flex-arrays=3 is coming and we need to land these changes
to prevent issues like these in the short future:

../fs/minix/dir.c:337:3: warning: 'strcpy' will always overflow; destination buffer has size 0,
but the source string has length 2 (including NUL byte) [-Wfortify-source]
		strcpy(de3->name, ".");
		^

Since these are all [0] to [] changes, the risk to UAPI is nearly zero. If
this breaks anything, we can use a union with a new member name.

The host stream position is updated when no_stream_position is set as 0.
However current implementation updates host stream position only when
report data is larger than or equal to host period size which is decided
by the period size of host side. It maybe cause host stream position
update not in time. Therefore this patch introduces another field
"cont_update_posn", a boolean value aimed to update host stream position
continuously and based on period size of pipeline. It can get better
precise when need to update host stream position from firmware.

fb6723daf8 ALSA: pcm: comment about relation between msbits hw parameter and [S|U]32 formats
Regarding to handling [U|S][32|24] PCM formats, many userspace
application developers and driver developers have confusion, since they
require them to understand justification or padding. It easily
loses consistency and soundness to operate with many type of devices. In
this commit, I attempt to solve the situation by adding comment about
relation between [S|U]32 formats and 'msbits' hardware parameter.

The formats are used for 'left-justified' sample format, and the available
bit count in most significant bit is delivered to userspace in msbits
hardware parameter (struct snd_pcm_hw_params.msbits), which is decided by
msbits constraint added by pcm drivers (snd_pcm_hw_constraint_msbits()).

In driver side, the msbits constraint includes two elements; the physical
width of format and the available width of the format in most significant
bit. The former is used to match SAMPLE_BITS of format. (For my
convenience, I ignore wildcard in the usage of the constraint.)

As a result of interaction between ALSA pcm core and ALSA pcm application,
when the format in which SAMPLE_BITS equals to physical width of the
msbits constaint, the msbits parameter is set by referring to the
available width of the constraint. When the msbits parameter is not
changed in the above process, ALSA pcm core set it alternatively with
SAMPLE_BIT of chosen format.

In userspace application side, the msbits is only available after calling
ioctl(2) with SNDRV_PCM_IOCTL_HW_PARAMS request. Even if the hardware
parameter structure includes somewhat value of SAMPLE_BITS interval
parameter as width of format, all of the width is not always available
since msbits can be less than the width.

I note that [S|U]24 formats are used for 'right-justified' 24 bit sample
formats within 32 bit frame. The first byte in most significant bit
should be invalidated. Although the msbits exposed to userspace should be
zero as invalid value, actually it is 32 from physical width of format.

ALSA: pcm: introduce INFO_NO_REWINDS flag
When the hardware can only deal with a monotonically increasing
appl_ptr, this flag can be set.

In case the application requests a rewind, be it with a
snd_pcm_rewind() or with a direct change of a mmap'ed pointer followed
by a SNDRV_PCM_IOCTL_SYNC_PTR, this patch checks if a rewind
occurred and returns an error.

Credits to Takashi Iwai for identifying the path with SYNC_PTR and
suggesting the pointer checks.

2dc26d98cf overflow updates for v5.16-rc1
The end goal of the current buffer overflow detection work[0] is to gain
 full compile-time and run-time coverage of all detectable buffer overflows
 seen via array indexing or memcpy(), memmove(), and memset(). The str*()
 family of functions already have full coverage.
 
 While much of the work for these changes have been on-going for many
 releases (i.e. 0-element and 1-element array replacements, as well as
 avoiding false positives and fixing discovered overflows[1]), this series
 contains the foundational elements of several related buffer overflow
 detection improvements by providing new common helpers and FORTIFY_SOURCE
 changes needed to gain the introspection required for compiler visibility
 into array sizes. Also included are a handful of already Acked instances
 using the helpers (or related clean-ups), with many more waiting at the
 ready to be taken via subsystem-specific trees[2]. The new helpers are:
 
 - struct_group() for gaining struct member range introspection.
 - memset_after() and memset_startat() for clearing to the end of structures.
 - DECLARE_FLEX_ARRAY() for using flex arrays in unions or alone in structs.
 
 Also included is the beginning of the refactoring of FORTIFY_SOURCE to
 support memcpy() introspection, fix missing and regressed coverage under
 GCC, and to prepare to fix the currently broken Clang support. Finishing
 this work is part of the larger series[0], but depends on all the false
 positives and buffer overflow bug fixes to have landed already and those
 that depend on this series to land.
 
 As part of the FORTIFY_SOURCE refactoring, a set of both a compile-time
 and run-time tests are added for FORTIFY_SOURCE and the mem*()-family
 functions respectively. The compile time tests have found a legitimate
 (though corner-case) bug[6] already.
 
 Please note that the appearance of "panic" and "BUG" in the
 FORTIFY_SOURCE refactoring are the result of relocating existing code,
 and no new use of those code-paths are expected nor desired.
 
 Finally, there are two tree-wide conversions for 0-element arrays and
 flexible array unions to gain sane compiler introspection coverage that
 result in no known object code differences.
 
 After this series (and the changes that have now landed via netdev
 and usb), we are very close to finally being able to build with
 -Warray-bounds and -Wzero-length-bounds. However, due corner cases in
 GCC[3] and Clang[4], I have not included the last two patches that turn
 on these options, as I don't want to introduce any known warnings to
 the build. Hopefully these can be solved soon.

407359d44e ALSA: firewire-motu: export meter information to userspace as float value
In command DSP models, one meter information consists of 4 bytes for
IEEE 764 floating point (binary32). In previous patch, it is exported
to userspace as 32 bit storage since the storage is also handled in
ALSA firewire-motu driver as well in kernel space in which floating point
arithmetic is not preferable. On the other hand, ALSA firewire-motu driver
doesn't perform floating point calculation. The driver just gather meter
information from isochronous packets and fill structure fields for
userspace.

In 'header' target of Kbuild, UAPI headers are processed before installed.
In this timing, #ifdef macro with __KERNEL__ is removed. This mechanism
is useful in the case so that the 32 bit storage can be accessible as u32
type in kernel space and float type in user space. We can see the same
usage in ''struct acct_v3' in 'include/uapi/linux/acct.h'.

This commit is for the above idea. Additionally, due to message
protocol, meter information is filled with 0xffffffff in the end of
period but 0xffffffff is invalid as binary32. To avoid confusion in
userspace application, the last two elements are left without any
assignment.

0f166e1257 ALSA: firewire-motu: refine parser for meter information in register DSP models
After further investigation, I realize that the total number of elements
in array is not enough to store all of related messages from device.
This commit refines meter array and message parser.

In terms of channel identifier, register DSP models are classified to
two categories:

1. the target of output is selectable

828mk2, 896hd, and Traveler are in the category. They transfer messages
with channel identifier between 0x00 and 0x13 for input meters,
therefore 20 elements are needed to store.

On the other hand, they transfer messages with channel identifier for one
pair of output meters. The selection is done by asynchronous write
transaction to offset 0x'ffff'f000'0b2c. The table for relationship
between written value and available identifiers is below:

=============  ===============
written value  identifier pair
=============  ===============
0x00000b00     0x80/0x81
0x00000b01     0x82/0x83
...            ...
0x00000b0b     0x96/0x97
...            ...
0x00000b10     0xa0/0xa1
...            ...
0x00000b3f     0xfe/0xff
...            ...
greater        0xfe/0xff
=============  ===============

Actually in the above three models, 0x96/0x97 pair is the maximum. Thus
the number of available output meter is 24.

2. all of output is available

8 pre, Ultralite, Audio Express, and 4 pre are in the category. They
transfer messages for output meters without any selection. The table for
available identifier for each direction is below:

==============  =========  ==========
model           input      output
==============  =========  ==========
8 pre           0x00-0x0f  0x82-0x8d
Ultralite       0x00-0x09  0x82-0x8f
Audio Express   0x00-0x09  0x80-0x8d
4 pre           0x00-0x09  0x80-0x8d
==============  =========  ==========

Some of available identifiers might not be used for actual output meters.

Anyway, 24 plus 24 elements accommodate the input/output meters.

I note that isochronous packet from V3HD/V4HD deliver no message.
Notification by asynchronous transaction to registered address seems to be
used for the purpose as well as for change of mixer parameter.

In support of enabling -Warray-bounds and -Wzero-length-bounds and

5aec579e08 ALSA: uapi: Fix a C++ style comment in asound.h
UAPI header should have no C++ style comment but only in the
traditional C style comment, but there is still one place we used it
mistakenly.  This patch corrects it.

b15706471a ALSA: firewire: Fix C++ style comments in uapi header
UAPI headers are built with -std=c90 and C++ style comments are
explicitly prohibited.  The recent commit overlooked the rule and
caused the error at header installation.  This patch corrects those.

ca15a09ccc ALSA: firewire-motu: add ioctl command to read cached parameters in register DSP model
This patch adds new ioctl command for userspace applications to read
cached parameters of register DSP.

The structured data includes model-dependent parameters. Userspace
application should be carefully programmed so that what parameter is
common and specific.
